For a pendant drop whose contact line is a circle of radius $r_0$, we derive the relation $mg\sinα={π\over2}γr_0\,(\cosθ^{\rm min}-\cosθ^{\rm max})$ at first order in the Bond number, where $θ^{\rm min}$ and $θ^{\rm max}$ are the contact angles at the back (uphill) and at the front (downhill), $m$ is the mass of the drop and $γ$ the surface tension of the liquid. The Bond (or Eötvös) number is taken as $Bo=mg/(2r_0γ)$. The tilt angle $α$ may increase from $α=0$ (sessile drop) to $α=π/2$ (drop pinned on vertical wall) to $α=π$ (drop pendant from ceiling). The focus will be on pendant drops with $α=π/2$ and $α=3π/4$. The drop profile is computed exactly, in the same approximation. Results are compared with surface evolver simulations, showing good agreement up to about $Bo=1.2$, corresponding for example to hemispherical water droplets of volume up to about $50\,μ$L. An explicit formula for each contact angle $θ^{\rm min}$ and $θ^{\rm max}$ is also given and compared with the almost exact surface evolver values.
